Abstract

The buffer store for a heat carrier has a thermal insulation at least at the tank mantle (4) as separate movable bands of thermal insulation blocks (3). At the outer side, they are supported by the surrounding tank mantle (4 and, at the inner side, they are covered by a watertight film (6).

Description

Die Erfindung bezieht sich auf einen Pufferspeicher für den Wärmeträger eines Wärmeverbrauchers, insbesondere eine Niedertemperaturheizung, mit einem eine Wärmeisolierung aufweisenden, lastabtragenden Behälter.The invention relates to a buffer store for the heat transfer medium a heat consumer, in particular a low-temperature heating, with a load-bearing container with thermal insulation.

Übliche Pufferspeicher bestehen aus einem lastabtragenden Stahlbehälter, der an der Außenseite eine Wärmeisolierung aufweist. Da die Wärmeschichtung des Wärmeträgers im Pufferspeicher zur Ausnützung höherer Temperaturen in den oberen Speicherschichten möglichst ungestört beibehalten werden soll, sind jedoch diese Stahlbehälter ungünstig, weil über ihren wärmeleitende Mantel ein Wärmeaustausch stattfindet. Es wurden zwar bereits Speicherbehälter aus Kunststoff vorgeschlagen, doch sind diese Kunststoffbehälter aufwendig, insbesondere für größere Speichervolumen. Bei Pufferspeichern mit größeren Speichervolumen sind außerdem die Transportschwierigkeiten zu beachten, wobei die mögliche Speichergröße häufig durch die Querschnitte der Zutrittsöffnungen zum Aufstellungsort bestimmt werden.Usual buffer stores consist of a load-bearing steel container, which has thermal insulation on the outside. Because the thermal stratification of the heat transfer medium in the buffer storage to utilize higher temperatures in the upper storage layers as undisturbed as possible should, however, these steel containers are unfavorable because of their heat-conducting Jacket heat exchange takes place. There were already storage tanks made of plastic, but these plastic containers are expensive, especially for larger storage volumes. For buffer tanks with larger ones Storage volume, the transport difficulties must also be taken into account, the possible storage size often through the cross-sections of the access openings be determined to the installation site.

Um einen Wasserbehälter in einfacher Weise mit einem Isoliermantel versehen zu können, ist es bekannt (DE 26 47 142 B1), den Isoliermantel aus einer aufwickelbaren Isoliermatte herzustellen, die einseitig mit gelenkig bewegbaren Isolierrippen versehen ist, so daß der Isoliermantel außen um den Wasserbehälter gewickelt werden kann. Hinsichtlich des Wärmeaustausches zwischen den unterschiedlich warmen Wasserschichten über die Behälterwand treten jedoch die bereits geschilderten Nachteile auf.To a water tank in a simple way with an insulating jacket To be able to provide, it is known (DE 26 47 142 B1), the insulating jacket to produce a roll-up insulating mat that can be moved on one side with articulated Insulating ribs is provided so that the insulating jacket around the outside of the water tank can be wrapped. Regarding the heat exchange between the different warm water layers over the tank wall however, the disadvantages already described occur.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Pufferspeicher für den Wärmeträger eines Wärmeverbrauchers, insbesondere einer Niedertemperaturheizung, der eingangs geschilderten Art so auszugestalten, daß einerseits ein einfacher Aufbau sichergestellt und anderseits ein Wärmeaustausch zwischen den Wärmeträgerschichten über den Behältermantel weitgehend unterbunden werden kann.The invention is therefore based on the object of providing a buffer memory for the heat transfer medium of a heat consumer, in particular a low-temperature heating, the type described in such a way that one hand a simple structure ensured and on the other hand a heat exchange between largely prevent the heat transfer layers via the container jacket can be.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Wärmeisolierung zumindest im Bereich des Behältermantels aus einzelnen, scharenweise versetzbaren Wärmedämmsteinen besteht, die sich an ihrer Außenseite am lastabtragenden, die Wärmeisolierung umschließenden Behältermantel abstützen und innen mit einer wasserdichten Folie abgedeckt sind.The invention solves this problem in that the thermal insulation at least in the area of the container casing from individual, in droves removable thermal insulation bricks, which are on the outside on support load-bearing container jacket enclosing the heat insulation and are covered inside with a waterproof film.

Da im Gegensatz zu herkömmlichen Speicherkonstruktionen der lastabtragende Behältermantel die Wärmeisolierung außen umschließt, und die Wärmeisolierung auf der Innenseite durch eine wasserdichte Folie abgedeckt wird, wird ein Wärmeaustausch zwischen Wärmeträgerschichten unterschiedlicher Temperatur über den Behältermantel unterbunden, ohne eine aufwendige Behälterkonstruktion in Kauf nehmen zu müssen. Es wird vielmehr ein einfacher Konstruktionsaufbau der Wärmeisolierung aus einzelnen, scharenweise versetzbaren Wärmedämmsteinen ermöglicht, weil die sich am äußeren Behältermantel abstützende Wärmeisolierung lediglich auf Druck beansprucht wird. Dies bedeutet, daß der lastabtragende Behältermantel unterschiedlich aufgebaut und beispielsweise durch eine Betonwanne gebildet werden kann, in die dann zumindest im Bereich des Behältermantels die Wärmeisolierung aus einzelnen Wärmedämmsteinen eingesetzt werden kann. Eine Bodenisolierung ist nur dann erforderlich, wenn über den Boden ein Wärmeabzug zu befürchten ist. Liegen die Temperaturen der untersten Wärmeträgerschichten im Bereich der Bodentemperatur bzw. darunter, so kann auf eine Bodenisolierung eines solchen Pufferspeichers vorteilhaft verzichtet werden, was im allgemeinen bei Speichervolumen über 10 m3 der Fall ist.In contrast to conventional storage constructions, the load-bearing Container jacket encloses the heat insulation on the outside, and the heat insulation is covered on the inside by a waterproof film, becomes a different heat exchange between heat transfer layers Temperature is prevented via the container jacket without an expensive container construction to have to put up with. Rather, it will be an easy one Construction structure of the thermal insulation from individual, displaceable in droves Thermal insulation blocks made possible because they are on the outer container jacket supporting thermal insulation is only subjected to pressure. This means, that the load-bearing container jacket is constructed differently and, for example can be formed by a concrete trough, in which then at least in the area of the container jacket, the thermal insulation from individual thermal insulation bricks can be used. Floor insulation is only required if if there is a risk of heat being extracted from the floor. Are they lying Temperatures of the lowest heat transfer layers in the area of the floor temperature or below, it can be on a floor insulation of such a buffer memory be advantageously dispensed with, which is generally the case with storage volumes over 10 m3 is the case.

Der Aufbau der Wärmeisolierung zumindest im Bereich des Behältermantels aus einzelnen Wärmedämmsteinen bietet die vorteilhafte Voraussetzung dafür, den Pufferspeicher nicht vorfertigen zu müssen, sondern erst am Aufstellungsort zusammenbauen zu können. Dies gilt insbesondere für Pufferspeicher mit einem metallischen Behältermantel, weil in diesem Fall der lastabtragende Behältermantel aus einem um den zylindrischen Wärmeisoliermantel gebogenen Blechband gebildet werden kann, dessen axiale Ränder miteinander zugfest verbunden werden. Zur Errichtung des Pufferspeichers ist daher zunächst der zylindrische Wärmeisoliermantel aus den einzelnen Wärmedämmsteinen aufzubauen, bevor das entsprechend abgelängte Blechband um den Wärmeisoliermantel gebogen wird und dann die aneinanderstoßenden Ränder des Blechbandes miteinander zugfest verbunden werden, beispielsweise durch das Setzen von Nieten. Die Dichtheit des Pufferspeichers wird durch die innere Folienauskleidung sichergestellt, so daß lediglich für einen entsprechend isolierten Behälterdeckel zu sorgen ist, durch den vorzugsweise die Leitungsanschlüsse geführt sind.The structure of the heat insulation at least in the area of the container jacket individual thermal insulation bricks offer the advantageous prerequisite for not having to prefabricate the buffer tank, but only at the installation site to be able to assemble. This applies in particular to buffer storage with a metallic container jacket, because in this case the load-bearing Container jacket made of a bent around the cylindrical thermal insulation jacket Sheet metal strip can be formed, the axial edges of which are tensile to one another get connected. To set up the buffer memory, the first is therefore to build cylindrical thermal insulation jacket from the individual thermal insulation bricks, before the correspondingly cut sheet metal strip around the thermal insulation jacket is bent and then the abutting edges of the sheet metal strip can be connected to each other with tensile strength, for example by setting Rivets. The tightness of the buffer storage is due to the inner foil lining ensured so that only for an appropriately insulated container lid to be taken care of, through which the line connections are preferably led.

Besonders einfache Konstruktionsverhältnisse ergeben sich, wenn die hintereinandergereihten Wärmedämmsteine zu ihrer gelenkigen Verbindung aus Schultern und Gegenschultern bestehende Scharnieransätze aufweisen, die auf ihren einander axial gegenüberliegenden Stirnseiten einerseits einen Gelenkzapfen und anderseits eine Zapfenaufnahme bilden. Durch diese Scharnieransätze werden zwischen den Wärmedämmsteinen gelenkige Verbindungen erreicht, die in einfacher Weise eine Anpassung des Wärmeisoliermantels an den jeweiligen Durchmesser des lastabtragenden Behältermantels erlauben, ohne die Wärmedämmsteine an unterschiedliche Behälterdurchmesser anpassen zu müssen. Die in die Zapfenaufnahmen eingreifenden Gelenkzapfen der Scharnieransätze ergeben darüber hinaus eine gegenseitige Verankerung der einzelnen neben- und übereinandergesetzten Wärmedämmsteine, wodurch der Aufbau des Wärmeisoliermantels aus den Wärmedämmsteinen ohne zusätzliche Verbinder erheblich erleichtert wird. Particularly simple design relationships result when the thermal insulation bricks lined up in series for their articulated connection Shoulders and counter shoulders have existing hinge lugs that open on their axially opposite end faces on the one hand a hinge pin and on the other hand form a cone seat. Through these hinge approaches articulated connections are achieved between the thermal insulation bricks, which can be easily adapted to the heat insulation jacket allow the respective diameter of the load-bearing container shell without the Adapt thermal insulation bricks to different container diameters have to. The pivot pins of the hinge lugs that engage in the pin receptacles also result in mutual anchoring of the individual juxtaposed and superimposed thermal insulation bricks, whereby the construction of the thermal insulation jacket from the thermal insulation bricks without additional connectors is made considerably easier.

Gemäß dem Ausführungsbeispiel der Fig. 1 besteht der dargestellte Pufferspeicher für den Wärmeträger eines Wärmeverbrauchers, insbesondere einer Niedertemperaturheizung, aus einer wärmeisolierenden, kreisförmigen Bodenplatte 1, auf der ein in sich geschlossener Wärmeisoliermantel 2 aus einzelnen Wärmedämmsteinen 3 scharenweise aufgebaut ist. Dieser Wärmeisoliermantel 2 ist auf der Außenseite von einem um den Wärmeisoliermantel 2 gebogenen Behältermantel 4 aus Blech umschlossen, dessen aneinanderstoßende Ränder miteinander zugfest verbunden sind, so daß über den Behältermantel 4 die hydrostatischen Kräfte abgetragen werden können. Auf der Innenseite ist die Bodenplatte 1 und der Wärmeisoliermantel 2 durch eine Auskleidung 5 aus einer wasserdichten Folie abgedeckt, wobei die Mantelfolie 6 mit der Bodenfolie 7 wasserdicht verschweißt sind. Der in dieser Art gebildete Pufferspeicher wird oben durch einen wärmeisolierenden Deckel 8 verschlossen, durch den beispielsweise die Anschlußleitungen 9 für einen Ladekreis, für den Vor- und Rücklauf einer Niedertemperaturheizung und für eine Brauchwasseraufbereitung geführt sind.According to the embodiment of FIG. 1, there is the one shown Buffer storage for the heat transfer medium of a heat consumer, in particular a low temperature heater, from a heat-insulating, circular Base plate 1 on which a self-contained thermal insulation jacket 2 made of individual Thermal insulation bricks 3 is built in droves. This thermal insulation jacket 2 is on the outside of a bent around the heat insulating jacket 2 Container jacket 4 enclosed in sheet metal, its abutting Edges are connected to each other in a tensile manner so that the container jacket 4 the hydrostatic forces can be dissipated. On the inside is the Base plate 1 and the heat insulating jacket 2 through a lining 5 from a waterproof film covered, the jacket film 6 with the bottom film 7 are welded watertight. The buffer memory formed in this way is closed at the top by a heat-insulating cover 8, for example by the the connecting lines 9 for a charging circuit, for the forward and return a low temperature heater and for domestic water treatment are led.

Um eine möglichst ungestörte Schichtung des Wärmeträgers im Pufferspeicher zu erhalten, weist dieser einen Ladeeinsatz 10 in Form eines Rohres mit über der Höhe verteilten Durchtrittsöffnungen auf, so daß der beispielsweise aus dem Ladekreis in das Rohr eintretende Wärmeträger aus dem Rohr in jenem Höhenbereich austritt, in dem die Schichttemperatur dem zugeführten Wärmeträger des Ladekreises entspricht. To ensure the stratification of the heat transfer medium in the buffer storage is as undisturbed as possible To obtain, this has a charging insert 10 in the form of a tube passage openings distributed over the height, so that, for example, from the heat transfer medium entering the tube from the tube in the tube Height range emerges in which the layer temperature of the supplied heat transfer medium of the charging circuit.

Da der Pufferspeicher drucklos betrieben wird, wird zur Vermeidung von Verdunstungsverlusten des Wärmeträgers der Wärmeträger mit einer auf dem Wärmeträgerspiegel schwimmenden Abdeckfolie 11 abgedeckt. Die auf dem Wärmeträgerspiegel schwimmende Abdeckfolie 11 läßt außerdem Änderungen des Füllstandes des Pufferspeichers zu.Since the buffer tank is operated without pressure, is to avoid Evaporation losses of the heat transfer medium with one on the heat transfer medium Heat transfer mirror floating cover sheet 11 covered. The one on the Heat transfer mirror floating cover 11 also allows changes the fill level of the buffer tank.

Wie insbesondere den Fig. 2 und 3 entnommen werden kann, greifen die hintereinandergereihten Wärmedämmsteine 3 mit Schultern 12 und Gegenschultern 13 ineinander ein, die Scharnieransätze bilden. Diese Scharnieransätze weisen auf ihren einander axial gegenüberliegenden Stirnseiten einerseits einen Gelenkzapfen 14 und anderseits eine Zapfenaufnahme 15 auf, so daß sich beim Aneinandersetzen der einzelnen Wärmedämmsteine 3 zwischen diesen eine gelenkige Verbindung ergibt. Diese gelenkige Verbindung erlaubt eine Anpassung des aus den Wärmedämmsteinen 3 errichteten Wärmeisoliermantels 2 an unterschiedliche Durchmesser des Behältermantels 4, wie dies der Fig. 3 unmittelbar entnommen werden kann. Um eine zusätzliche Verbindung zwischen den einzelnen Wärmedämmsteinen 3 übereinanderliegender Steinscharen zu erhalten, können auf der Unterseite der Wärmedämmsteine 3 Nuten 16 vorgesehen werden, die mit Federn 17 auf der Oberseite der Wärmedämmsteine 3 zusammenwirken.As can be seen in particular from FIGS. 2 and 3, the Thermal insulation bricks 3 lined up with shoulders 12 and counter shoulders 13 into each other, forming the hinge lugs. These hinge lugs have one on their axially opposite end faces Hinge pin 14 and on the other hand a pin receptacle 15 so that when Put the individual thermal bricks 3 between them one articulated connection results. This articulated connection allows adjustment of the thermal insulation jacket 2 erected from the thermal insulation bricks 3 different diameters of the container casing 4, as shown in FIG. 3 directly can be removed. To provide an additional link between the to obtain individual thermal insulation bricks 3 overlapping stone shares, 3 grooves 16 can be provided on the underside of the thermal insulation bricks be that cooperate with springs 17 on the top of the thermal insulation bricks 3.
